Abstract
The utility model relates to a composite anchor rod and belongs to the technical field of geotechnical engineering. The composite anchor rod is composed of a barbed steel tube anchor rod body (1), an integral tensile rod piece (2) and a sleeve (3), wherein the integral tensile rod piece (2) is arranged in the barbed steel tube anchor rod body (1) and is made of a reinforcing steel bar or a high-strength steel strand, one section of the integral tensile rod piece (2) is sleeved with the sleeve (3), and the integral tensile rod piece (2) is divided into a free section and an anchorage section by the sleeve (3). The composite anchor rod has the advantages that the structure is simple, and operation is convenient; the construction efficiency of a permanent soil slope supporting project is greatly improved, the construction method of the permanent soil slope supporting project is simplified, the supporting effect of a permanent soil slope is effectively improved, and the supporting cost of the permanent soil slope is greatly lowered.
Description
Technical field:
The utility model relates to a kind of Composite Bolt, belongs to Geotechnical Engineering field.
Background technology:
Existing barbed implantable steel tube anchor rod, operation is simple.But its uplift resistance is less, be only applicable to provisional compared with shallow foundation hole and low soil-slope support engineering.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency of prior art, and provides a kind of simplification permanent compared with high soil slope supporting method, improves engineering construction efficiency, effectively improves permanently compared with high soil slope supporting effect, reduces the Composite Bolt of support cost.
Composite Bolt of the present utility model is to have obtained the improvement on the basis of patent (ZL201120050829.4) of power the inventor.
Composite Bolt of the present utility model, by barbed steel pipe anchor rod (1), be placed in the globality tension rod member (2) of making of reinforcing bar or high strength steel strand in barbed steel pipe anchor rod (1), be enclosed within a section of globality tension rod member (2) upper and the pipe box (3) that globality tension rod member (2) is divided into free segment and anchoring section is formed.
Operating principle of the present utility model: (1) effect of barbed steel pipe anchor rod is to replace anchor pole pore-forming, and the slurries that make are full of around Composite Bolt, for Composite Bolt provides uplift resistance; Globality tension rod member (2) is the stressed member of Composite Bolt, adopts as required sleeve pipe (3) that globality tension rod member (2) is divided into free segment and anchoring section, and free segment provides distortion for Composite Bolt, and anchoring section provides uplift resistance for Composite Bolt.
The utility model adopts the material of market sale to prepare according to a conventional method.
The utility model has the advantage of: simple in structure, easy to operate; Greatly improve the efficiency of construction of permanent soil-slope support engineering, simplified the construction method of permanent soil-slope support engineering, effectively improved permanent soil-slope supporting effect, greatly reduced the support cost of permanent soil-slope.
Accompanying drawing explanation:
Accompanying drawing is main TV structure schematic diagram of the present utility model.
The specific embodiment:
1, Composite Bolt of the present utility model as shown in drawings.By barbed steel pipe anchor rod 1, be placed in the globality tension rod member 2 of making of reinforcing bar or high strength steel strand in barbed steel pipe anchor rod 1, be enclosed within a section of globality tension rod member 2 upper and the sleeve pipe 3 that globality tension rod member 2 is divided into free segment and anchoring section is formed.The utility model adopts the material of market sale to prepare according to a conventional method.
2, the implantation of barbed steel pipe anchor rod 1
Adopt pneumatic dth hammer that " the barbed steel pipe anchor rod " 1 of making implanted in soil layer by predetermined inclination and orientation.
3, grouting
Adopt grouting equipment that cement grout is poured into anchor pole from barbed steel pipe anchor rod 1 external port.
4, the globality tension rod member 2 that packages sleeve pipe 3 is inserted in barbed steel pipe anchor rod 1, complete the construction of Composite Bolt.
Through reality, use and show, the utility model reaches designing requirement completely.
Claims (1)
1. a Composite Bolt, it is characterized in that by barbed steel pipe anchor rod (1), be placed in the globality tension rod member (2) of making of reinforcing bar or high strength steel strand in barbed steel pipe anchor rod (1), be enclosed within one section of pipe (3) formation that goes up and globality tension rod member (2) is divided into free segment and anchoring section of globality tension rod member (2).
